Abstract

A transformerless microinverter is described that is intended for integration into building materials such as residential roof shingles. The inverter achieves low profile (3 mm), high efficiency (95.1%) and high reliability capacitive energy storage using 125degC ceramics. It is intended to interface a 25 W photovoltaic array such as a small thin-film residential roof shingle to the 120 V AC utility. Design tradeoffs involving cost and efficiency are described, and operation of an experimental prototype is documented.
